Degrees are a unit that measures angles. A full rotation in degrees is equal to . By convention, degrees are measured starting from the rightmost edge of the circle with the positive direction corresponding to counterclockwise rotation.
Shown below are some common angles measured in degrees. These angles are common since they divide a full rotation into equal parts.
While angles are often introduced using the degree angle system, later in math, angles are typically measured using the radian angle system^{[1]}. To convert an angle from degrees to radians, multiply by the circle constant (tau) and divide by degrees^{[2]}. For example, to convert 60 degrees to radians multiply by tau, which is approximately equal to 6.28318530718, and divide by 360.
